Operations established store 4011 at 1:45 PM with an initial luminosity of 78.71E30.

Pbar, NuMI, and the Main Injector (MI) were set up to stack and send beam to NuMI at 2:26 PM. The first attempt to do this resulted in a NuMI trip. However, at 3:28 PM Operations successfully sent beam to Pbar and NuMI.

NuMI experts ended their study at 6:09 PM. Operations had Pbar switched back to normal stacking by 6:28 PM.

A NuMI expert began a study period at 4:17 PM and a Recycler expert began a study a minute later.

At 4:19 PM, BRF17 tripped off twice in two minutes. It reset okay, but then at 4:25 PM, it tripped off for the first of six times in thirty minutes. It was left off for a few minutes and then turned back on at 5:07 PM.

At 4:33 PM, Operations was informed that ten NuMI vacuum pumps had tripped off. The pumps were all turned back on.

At 5:14 PM, BRF17 & 18 tripped off. They both reset okay.

At 5:16 PM, a Linac RF station (KRF5) tripped off for the first of two times in fifteen minutes. It reset okay both times.

At 6:27 PM, BRF6 tripped off for the first of four times. It reset okay each time.

Operations terminated store 4011 at 7 PM and then put the TeV into shot setup.

At 9:04 PM, the TeV suffered a quench at sector B4. Operations investigated and discovered that the skew quadrupole's power supply (T:SQ) had failed. An expert was called in to make repairs.

At 3:57 AM, LRF3 tripped off. Operators investigated and then called in an expert.

TeV studies ended at 4:44 AM.

Operations reported at 6 AM that the H- Source began having a problems. Operators investigated and then called in experts.

The Plan for Wednesday
The plan for today is to get the source working enough to get at least a small amount of beam to the TeV for study purposes and stacking. A shot setup will follow as soon as the TeV completes its study or the stack reaches 150mA.
